Ammonium sulfate yog ib qho zoo heev nitrogen chiv (feem ntau hu ua chiv hmoov), haum rau cov av thiab cov qoob loo. Nws tuaj yeem txhawb kev loj hlob ntawm cov ceg thiab nplooj, txhim kho cov txiv hmab txiv ntoo zoo thiab tawm los, thiab txhim kho cov qoob loo tiv thaiv kev puas tsuaj. Nws tuaj yeem siv tau los ua cov chiv chiv, tshuaj pleev ib ce, thiab cov noob chiv. Hauv qab no, peb yuav qhia tsib qhov kev ceev faj tseem ceeb rau kev thov ammonium sulfate.
1. Sim tsis txhob siv ammonium sulfate rau cov nplej
Vim tias nyob rau hauv dej nyab, cov av yuav muaj kev mob hypoxia, thiab tom qab siv ammonium sulfate, sulfate ions hauv nws yuav raug txo kom sulfides. Kev sib sau ntawm cov tshuaj sulfide ntau dhau tuaj yeem ua rau cov nroj tsuag puas tsuaj thiab tuag.
2. Ammonium sulfate belongs rau acidic chiv, thiab daim ntawv thov mus sij hawm ntev tuaj yeem txhim kho cov acidity ntawm cov av. Yog li ntawd, ammonium sulfate tsis haum rau daim ntawv thov ntawm acidic av. Thaum thov rau cov av acidic nyob rau sab qab teb, yuav tsum tau them nyiaj mloog mus rau kev sib txuas ntawm daim ntawv thov ntawm cov ntoo tshauv, phosphate pob zeb hmoov, calcium magnesium phosphate fertilizer, thiab lwm yam. Thaum siv rau calcareous av nyob rau hauv sab qaum teb, yuav tsum tau them nyiaj mloog mus rau kev sib xyaw daim ntawv thov. organic chiv los tiv thaiv kev tsim ntawm insoluble calcium sulfate los ntawm kev sib xyaw ntawm calcium ions thiab sulfate ions hauv av, uas tuaj yeem ua rau cov av compaction.
3. Ammonium sulfate tuaj yeem siv los ua cov chiv chiv, noob chiv, thiab tshuaj pleev ib ce
Thaum siv cov chiv hauv paus, nws yog ib qho tsim nyog yuav tsum tau siv cov av sib sib zog nqus los pab cov qoob loo nqus. Thaum ua cov noob chiv, daim ntawv thov yuav tsum tsis txhob loj heev thiab yuav tsum tsis txhob ntau tshaj 3 kilograms ib evkawj. Topdressing yog txoj kev tsim nyog tshaj plaws, thiab tus nqi ntawm ammonium sulfate topdressing yuav tsum tau txiav txim siab raws li ntau hom av. Rau cov av uas tsis muaj dej tsis zoo thiab cov chiv khaws cia, nws yuav tsum tau siv rau hauv cov theem, thiab tus nqi yuav tsum tsis txhob ntau dhau txhua zaus; Rau cov av uas muaj dej zoo thiab cov chiv khaws cia, qhov ntau npaum li cas tuaj yeem nce ntxiv txhua lub sijhawm. Tus nqi ntawm cov av noo kuj tseem muaj feem cuam tshuam rau kev siv chiv, tshwj xeeb tshaj yog nyob rau hauv cov av qhuav. Thaum thov ammonium sulfate, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau dej raws sijhawm. Thaum ua ntawv thov topdressing nyob rau hauv paddy teb, nws yog ib qhov tsim nyog los ua ntej ntws thiab qhuav cov av, thiab xyuam xim rau siv nws ua ke nrog plowing thiab raking.
4. Tsis haum rau kev siv mus sij hawm ntev ntawm ammonium sulfate rau tib thaj av cultivated
Nws tsis pom zoo kom siv ammonium sulfate rau tib thaj av cog rau lub sijhawm ntev, txwv tsis pub cov av yuav acidic thiab tawv. Yog tias tsim nyog siv nws, ib qho tsim nyog ntawm txiv qaub lossis organic chiv tuaj yeem siv ua ke. Txawm li cas los xij, nws yuav tsum raug sau tseg tias ammonium sulfate thiab txiv qaub tsis tuaj yeem sib xyaw kom tiv thaiv ammonium sulfate los ntawm decomposing thiab ua rau nitrogen poob. Feem ntau, daim ntawv thov ua ke ntawm ob yuav tsum sib cais los ntawm 3-5 hnub.
5. Ammonium sulfate tsis tuaj yeem siv rau hauv kev sib cuag lossis sib xyaw nrog lwm cov alkaline chiv lossis tshuaj
Ammonium sulfate chiv tsis tuaj yeem siv rau hauv kev sib cuag lossis sib xyaw nrog lwm cov tshuaj alkaline lossis tshuaj tiv thaiv kom tsis txhob muaj cov tshuaj txo qis.
